● DC current, DC voltage
*•The O
2 sensor is manufactured by one of the following companies: Nihon Gaishi (NGK), Marathon
Monitors, Cambridge, Corning, AACC (Advanced Atmosphere Control Corporation), Barber
Colman or Furnace Control.
•PV2 in models with carbon potential compensation is tied to the O
2
sensor.
Handling Precautions
•The unit for code Z06 is “K” (kelvin).
•Code F50 and P50 do not generate the PV lower limit alarm.
•The number of decimal digits for DC current and DC voltage is
programmable from 0 to 4.
•The O
2 sensor generates the PV upper limit alarm at values of 1375mV or
above, but does not generate the PV lower limit alarm.
